Computer scientist Peter Gutmann tells The Reg why it's 'bollocks' The US National Institute for Standards and Technology (NIST) has been pushing for the development of post-quantum cryptographic ...

Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

Quantum computing is generating a lot of excitement in the tech world right now. Following several recent breakthroughs, this once theoretical technology is increasingly accessible to researchers and ...

In the world of quantum error correction, an underdog is coming for the king. Last week, new simulations from two groups reported that a rising class of quantum error ...
